5, Select the FALSE statement about lipids and membranes. A) Triacylglycerols are the primary lipid found in membranes. B) In aqueous solution triangular shaped single-tailed fatty acids form micelles. In aqueous solution cytindrical shaped double-tailed fatty acids form lipid bilayers. D) Alipid bilayer can fono a closed self-sealing vesicle with an interior aqueous compartment. E) van der Waals interactions between the hydrocarbon tails of the lipids that fomm a membrane help stabilize the membrane. 6. Considering the citric acid cycle steps between citrate and succinate. how many total high- energy phosphate bonds, or met ATPmolecules, can be generated from the energy extracted in these steps? Answer for ONE molecule of citrate Assume oxidative phosphorylation is occurring A) 4 B) 8 C) 6 D) 5 E) 7 7. What enzyme of the citric acid cycle is responsible for the following reaction? Citrate lsocitrate A) socitrate synthase B) citrate synthase C) isocitrate dehydrogenase aconitase D) E) isocitrate isomerase 8. Select the FALSE statement about biological membranes. A The low incidence of protein flip-flop in a membrane preserves membrane asymmetry. B) are of and that are held noncovalent interactions. because the Membranes are generally impermeable to nonpolar molecules interior of the D) is hydrophilic. than the other Membranes can be electrically polarized with one side more negative E) Membranes are self-sealing.
